Webfunction was proven collision-resistant under the assumed hardness of the modi-fied average-case problem, called Ideal-SIS. The latter was itself proven at least as hard as the restrictions of standard worst-case lattice problems to a specific class of lattices (called ideal lattices). In 2009, Stehlé et al.
